Semaglutide API Supplier India | CAS 910463-68-2 | Bulk Peptide API

Semaglutide is a 31-amino-acid GLP-1 analogue carrying a C18 fatty diacid side chain attached via a linker at position 26. That acylation is what gives the molecule its extended half-life, and it is also the part of the synthesis where quality varies most between sources.

Semaglutide Specifications

Quality Documentation — What to Request

Ask specifically for the related substances profile rather than a headline purity figure. Des-amino and acylation-position isomers are the impurities that distinguish a well-controlled synthesis from a poor one, and they will not show up in a single purity number. Standard requests are HPLC purity, peptide content, related substances, residual solvents and water content.

Import, Licensing & Logistics

Semaglutide has the most complex regulatory position of any peptide in this catalogue. Patent protection remains active in several major markets and expires on different dates by territory. Confirm the position for your specific destination before committing to a commercial order, since import seizure risk sits with the buyer.

Who Buys Semaglutide API

Pharmaceutical developers, research organisations and formulation companies working with GLP-1 analogues in territories where this is permitted.

Acylation Site and Isomer Impurities

Semaglutide carries a C18 fatty diacid chain attached through a linker at position 26, and that acylation step is where synthesis quality varies most between sources. The impurities that matter are des-amino forms and acylation-position isomers, neither of which appears in a headline purity figure. Request the related substances chromatogram rather than a summary number, and have your analytical team confirm the method resolves positional isomers.

Stability, Storage & Retest

Lyophilized peptides are stable at minus twenty degrees Celsius but degrade measurably at ambient temperature over weeks rather than months. The cold chain must hold from despatch to receipt, and a temperature logger in the consignment is the only way to verify it did. Once reconstituted, stability is measured in days. Water content by Karl Fischer matters because residual moisture accelerates degradation during storage.

Export Process & Lead Time

Peptide consignments require cold-chain air freight with temperature logging, which restricts routing and carrier options and raises freight cost substantially relative to ambient shipment. Customs clearance for lyophilized peptides is slower than for conventional APIs in several markets because the classification is less familiar to inspectors, and a consignment held at ambient temperature during a clearance delay may arrive out of specification. Build clearance time into planning and confirm the destination classification before despatch.

Incoming Goods Inspection

Incoming checks should cover appearance, HPLC purity against the supplied chromatogram, peptide content and water content. Peptide content is the figure that determines what you have actually bought: material quoted on gross weight rather than net peptide content can differ by fifteen to twenty per cent from what the label implies, and that difference will not appear in a purity figure.

Frequently Asked Questions

What documentation comes with Semaglutide API?

Batch Certificate of Analysis, product specification and SDS where available for the specific source, plus export documentation including country of origin certificate for international consignments.

What is the minimum order quantity?

MOQ depends on specification, packaging and destination. Send your requirement and we will confirm the applicable minimum with your quotation.

Can you ship Semaglutide API to my country?

Import permissions differ by destination and several markets restrict this material. Confirm your national requirements before ordering and we will advise whether we can supply into that territory.

How is pricing determined?

Pricing reflects quantity, specification, packaging and destination. Send your full requirement rather than a quantity alone so the quotation is accurate.
